This remind me of my CDG-ATL a while ago. Purser announced correctly in French that we’ll arrive at Terminal I, while in English she pronounced that letter in French sounding like E in the English language. Before landing, the guy behind me was confused by the Mobile Passport Control app if he should mark Terminal E or F, while AF shows as arriving at I. FA had no clue so I turned around and told him AF will always use F. After landing, he muttered something about the FA announcing E…

For those who aren’t familiar with my home base:
ATL has “Terminal I” which refers to the landside area of the building that is physically Concourse F. All intl carriers use F for arrivals, which is where immigration and all formalities happen for all pax. With DL, you might park at Concourse E or F. If arriving at E, transit pax complete all formalities in E while ATL bound pax follow signs and take a long walk to F.
